I've been working on a c++ interface to capture images from all types of webcams via the Micrsoft Media Foundation. I've already got a bit of code that can connect with several types of webcams and is able to capture images in different resolutions and formats.
I know that under WinXP it is possible to change different parameters of the webcam (like white balance, exposure time e.g.) by using the Direct Show library. Unfortunately the interface in the Direct Show library that made it possible to easily capture single frames from a webcam is removed from Direct Show under Win7. Does anybody know how I can acces these parameters using Microsoft Media Foundation or any other library that I can combine with the Microsoft Media Foundation?
DirectShow is still good in Windows 7 (the easiest to check is using GraphEdit and AMCap from Windows SDK). Media Foundation however lacks essential support in earlier versions of Windows.
